A couple of weeks ago my JW sister in law made a remark about the advantage of Zoom meetings. " You tune in...you watch a few videos and you're done ! " As she said "done" she brushed her hands together as if dusting them off and flung them outward as one would do when completing a unpleasant but necessary task.
A lot of JW's go to meetings not because they can't wait to hear something new and interesting. They often go out of obligation, habit or peer pressure and because they mostly want to see their friends. It seems to me that little by little it's getting easier and easier for them to envision their lives without the JW's. It would be disheartening to make the effort to go to the Hall and see it half empty and find that none of the people you actually like are there. On top of that, to have your temperature taken and sit there for 2 hours with a mask on, this includes the already fidgety kids who would rather be elsewhere. What about commenting? You'd have to mumble through a mask. To remove it would expose the microphone holder and those around you to "droplets" and defeat the whole purpose of wearing the mask.
